If you are in business you will know the importance of making a sale whether that is of goods or a service. Lawyers & solicitors can offer legal advice on the legal aspects of your business, so you might not think they would know much about sales, yet they are in business too; the business of giving legal advice, but that is still a business. So they may well have been able to help you out with some tips.
During prime business hours decision makers are usually really busy. So make your calls to prospects outside of those hours. Try 8am before the frantic rush starts or 6pm when it has wound down and your decision maker is more relaxed.
